WATER-HEATING GAS-RADIATOR.

Specification of Letters Patent.

Patented Mar. 1, 1921.

Application filed june 30, 1920. Serial No. 393,019.

To all whom it may camera:

Be it known that' I, FRANK T. SoHLoTz- HAUER, a citizen of the United States, and a resident of the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Water-Heating Gas-Radiators, of which the following is a specification.

The present invention relates to a combined gas radiator and water heating system and has for its object to provide in combination with a standard and efiicient form of gas radiator, means for quickly heating a supply of water and for distributing the heated water to remote discharge apparatus and to remote heating means such as hot water radiator.

A further object of the invention is to provide, in combination with a gas radiator having a front or curtain of radiant burners, means located in close juxtaposition to i the curtain of burners to derive heat therefrom so that a supply of water can be quickly heated and delivered as required.

A further object of the invention is to provide, in combination with a radiant curtain gas radiator, Water heating means consisting of separate chambers interconnected to maintain a local circulation of water as it is heated and, in this connection, it is a further object of the invention to provide a check valve to control a directional flow of the water through the system and also to provide a safety device to prevent accidents due to excessive pressure.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be made manifest in the following description of the preferred form of the invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that it is not intendcd to limit the invention to the embodiment shown by the said drawings and description as variations may be adopted within the schpe of the invention as set forth in the claim.

Referring to the drawings:

Figure l is a front elevation of an improved type of radiant burner gas radiator or heater with which the Present invention is combined.

Fig. 2 is a vertical transverse section from the front to the back of the heater showing in diagrammatic connection thereto hot water distributing and hot water heat radiatin means.

ig. 3 is a diagrammatic view of the tank connections.

There is now in common use a highly efiicient form of gas radiator in which there is a front wall or curtain of burner means that becomes incandescent during combustion of fuel and in this form of radiator there is provided a chamber usually having in the back of the radiant curtain a fire resistance lining. In the present invention this lining is removed and there is substituted in its place means arranged adjacent to the curtain for heating and circulating water that may be utilized for various purposes as desired and that may also be utilized to heat various chambers by means of hot water radiators through which the heated water is circulated.

In the illustrated embodiment of the invention one type of radiator is shown comprising an ornate front frame 2 in which there is mounted a curtain 3 or other suitable wall formation of porous material, such as porcelain, that will become highly heated during the combustion of fuel adjacent the curtain forming part. At the rear of the frame? is provlded a box-like chamber 4 of comparatively shallow depth and suitable width and height. Such radiators are adapted'generally to be arranged in juxtaposition to fire-places in rooms although of course it is understood that they need not be S05 arranged in fire-places.

For the purpose of utilizing the highly efficient curtain to heat water there is arranged within the box-like chamber 4 water heating means comprising preferably a cold water upper tank 5 to which is connected a water supply pipe 6. The tank 5 is connected to an intermediate chamber 7. A primary heating tank is introduced behind the curtain 3 and in front of the rear tank 7. Such a primary tank is indicated at 8 and is connected at its lower portions at 9 to communicate with the tank 7 so that water can flow from the latter into the bottom of the primary heating tank 8 and this is provided at its upper end with an outflow connection 10. To the outflow connection there may be attached a pipe 11 delivering the heated water to various apparatus as, for

instance, to sinks, laundry trays, wash bowls or bath tubs as indicated at 12, and the heated water can also be led to a hot water radiator 13.

Circulation of the water from the radiator 13 is secured by a return pipe. 14 therefrom leading to the heating means in the radiator.

By means above described the hot water from the primary heating tank 8 may pass directly to the different apparatus attached to the hot water pipe 11 so that water of the highest degree in the heating system can be utlllzed and for the purpose of maintaining the water at the highest practical temperature during the operation of the radiator a local circuit is provided between the tanks 7 and 8 through means of across connection 15 inlthis case shown as tapping into the outlet 10 from the primary heater 8. The passage of cold water through the cross connection 15 is prevented by means of a check valve 16 provided in the cross connection.

The area of intercommunicating connection 9 between the tanks 7 and 8 is preferably larger than the. cross sectional area of the supply connection 6 and the outlet connection 10 thus securing a free flow of water from the rear into the front chamber.

The cold water pipe 6 discharges well toward the bottom of the 'top tank 5 as shown in Fig. 3 and a stand-pipe 17 opens near the top of tank 5 thus taking out the warm water produced by heating this tank. The pipe 17 leads into the top of the back tank 7.

A check valve 14' may be utilized in the pipe 14 to prevent the flow of hot water from the heating tanks toward the radiator.

What is claimed is The'combination with a gas radiator having a front curtain of radiant refractory burner units, of a warming tank connected to a water service pipe, aprimary tank adjacent the front curtain, an intermediate circulating tank supplied from the warming tank and discharging to the primary tank, and a distributing pipe system leading from the latter, and returning to the intermediate tank, and a box inclosing all of the tanks.-

In testimony whereof I have hereunto set my hand.

FRANK T. SCHLOTZHAUER.
